BEGULATING DEVICE FOR BOAD-SPRINKLERS. 7

Specification of Letters Patent.

Patented May 2 0, 1919.

Application filed October 4, 1916. Serial No. 123,642.

To all whom it may concern:

Be it known that I, GUSTAV SOHLATTER, a citizen of the Swiss Republic,and resident of Steinach, Switzerland, have invented a new and usefulRegulating Device for Road- Sprinklers, of which the following is aspecification.

, My invention relates to a device by means of which the sprinklingwidth as well as the output of road. sprinklers can be regulatedindependently. The device comprises a valve which is adapted to revolveand slide in a sprinkler head, thereby opening and closing certain ofthe perforations in said more cylinders which are connected by pairs ofcylindrical, diametrically opposite sectors of the same diameter. Whenthe valve is axially displaced in the sprinkler head, its cylinders willopen or close a greater or lesser number of perforations, therebyreducing or increasing the output. The sprinkling width is regulated byrevolving the valve.

device, therefore, can easily be manipulated so that the valve as wellas its operating mechanism is not exposed to'undue strain.

Reference is to be had to the accompanying drawings in which I haveillustrated two forms of my invention by way of example.

Figure 1 is a longitudinal and Fig. 2 a cross section on line Aw-B of asprlnkler head provided with a valve having two cylinders and twointermediate sectors, and Fig. 3 is an elevation with parts'in section,showing a' sprinkler head with a valvehaving three cylinders and fourintermediate sectors.

As clearly shown in Fig. 1, the regulating valve in the sprinkler head 1is formed by two cylinders 5 and 5 and two sectors 6 oflike crosssection in a sleeve 23 to turn in a suitable bearing 24 on the car and 6connecting them. The sprinkler head has two groups of perforations, 3and 3 and a hollow stud 4: which constitutes the'flushmg nozzle.

In the examples shown, the water is admitted at one end of the sprinklerhead, and the cylinders or pistons are made with longitudinal ducts oropenings, so that water may pass from the water inlet to the severaloutlets. The sectors as well as the cylinders connected thereby havecylindrically curved surfaces controlling the outletsror egress means. Ii

As mentioned above, the output of the sprinkler is regulated bydisplacing the valve axially in the head '1 while its sprinkling widthis regulated by revolving said valve. The axial movement of the valve iseifected'by means of a double-armed lever v16 which is preferablyarranged at or near the. drivers seat. This lever is, by a rod 17connected to another double-armed lever 18 which is mounted to pivotabout a'pin 20 supported on the car frame. The forked end 19 of thislever engagesa sleeve 21 on the rod 15 of the regulating valve. Bymoving lever 16, the valve is displaced axially so that its cylinders 5and 5 open or close the perforations of group 3 and simultaneously thoseof group 3 thereby regulating the In order to regulate the sprinklingwidth, the valve must be revolved in the sprinkling head so that thesectors 6 and 6 open or close certain of the perforations in groups 3and 3 which have been left open by cylinders 5 and 5 At the end of rod15 there is a portion of square cross section which passes with'asliding fit through an opening mounted frame but held againstlongitudinal movement. Fixed on this sleeve is a lever 25 to which islinked a rod 12. The other end of this rod is engaged by an angularlever 10,

11 which, in turn, is connected by the link 9, to the arm 8 of abell-crank'lever'Y, which,

like the lever 16, is arranged near the drivers seat.

\Vhen it is desired to opera output of the sprinkling head.

y te the flushing V nozzle, the valve is, by means of levers 7 and 16,placed in such position as to cover all the perforations 3 and 3whereupon, by further manipulation of lever 16, the valve is pushed tothe left until nozzle at is laid open.

In the modification illustrated in Fig. 3 a third cylinder 5 isconnected to the cylinders 5 and 5 by means of additional sectors 6 and6 This third cylinder and its sectors may serve for any purpose. Forexample, they may control another flushing nozzle 4 and regulate theoutput and sprin kling width of a further group of perforations 3 whilegroups 3 and 3 and the flushing nozzle 4 are regulated by cylinders 5and 5 and sectors 6, 6 Any other number of cylinders and sectorsconnectingthem may be provided.

The arrangement of two or more cylinders gives a good guiding to thevalve and, in connection with the diametrically opposite arrangement ofthe sectors and consequent relieving of the valve from one-sidedpressure, causes the valve to work smoothly when sliding as well as whenrevolving. Since the several regulating operations are effected byseparate sections of the valve, the relative position of theperforations and of the flushing nozzle can easily be varied. Bycombining as many cylinders and sectors as is practicable, I provide avalve by which a corresponding number of regulations may be effected. Asthe valve may be moved to either side and revolved in either direction,its regulating action can be varied in many ways.

I claim:
